We look at the division of 77186207 by 493 
The aim is to understand the frequency of 493 in 77186207.

Let's proceed to step 1:
If we divide 7 by 493, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 493

On to step 2:
The number 493 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 493

Step 3:
If we divide 771 by 493, we get 1 and a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 278 after subtracting 493 from 771.
Include the next digit (8) from the dividend after 278, then repeat: 2788 / 493

Moving on to step 4:
493 can be fit into 2788 5 times, resulting in a remainder of 323.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2465 from 2788, we get 323.
Include the next digit (6) from the dividend after 323, then repeat: 3236 / 493

Let's proceed to step 5:
If we divide 3236 by 493, we get 6 and a remainder of 278.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Deduct 2958 from 3236 and we're left with 278.
Include the next digit (2) from the dividend after 278, then repeat: 2782 / 493

Advancing to step 6:
The number 493 fits into 2782 5 times, leaving a remainder of 317.
The number 5 becomes the next digit in our result. 
Result so far: 1565.0
Subtracting 2465 from 2782 leaves us with 317.
Include the next digit (0) from the dividend after 317, then repeat: 3170 / 493

Advancing to step 7:
3170 divided by 493 is 6 with a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 15656.0
The remainder is 212 after subtracting 2958 from 3170.
Bring next digit (7) of the dividend behind the 212 and repeat the process: 2127 / 493

Let's proceed to step 8:
493 goes into 2127 4 times with a remainder of 155.
Record the quotient 4 as the next digit in the result. 
Result so far: 156564.0
Subtract 1972 from 2127 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
493 can be fit into 1550 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 156564.3
Subtracting 1479 from 1550 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
493 can be fit into 710 1 times, resulting in a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 156564.31
Deduct 493 from 710 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 11:
If we divide 2170 by 493, we get 4 and a remainder of 198.
Use 4 as the next digit of our solution. 
Result so far: 156564.314
If we take 1972 away from 2170, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 12:
If we divide 1980 by 493, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 156564.3144
If we take 1972 away from 1980, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 156564.3144 and a remainder of 8e-05.
